When it came to the day when he agreed with the Great Elder to repair the desolation, Lin Xingyu went out of the room early in the morning and went straight to the sword casting room, a little earlier than the agreed time, and when he arrived at the sword casting room, the Great Elder was already inside, squatting on the ground fiddling with the soul corpse, four masks and some other materials, preparing for the restoration of the desolation.

"Great Elder, it's early!" Lin Xingyu greeted.

"Well, go pull the bellows, the fire. The Great Elder responded lukewarmly, concentrating on selecting the materials.

The fire in the four furnace eyes is booming, and it seems that it has not been long since the previous person ran out, so Lin Xingyu was omitted from the steps of starting the fire.

When the Great Elder had prepared all the things, he placed the broken barren barren pieces side by side on the furnace and burned them over a large fire.

"There are many ways to cast a sword, usually the steps are smelting, casting, precision forging, repairing, forming, to see whether the finished product is good or not, the most critical step is precision forging, the initial shape of the cast sword needs to be deeply processed, and the processing process is particularly important.

Generally speaking, in this step, most of the methods used are the glued steel method, the steel clamping method or the steel-clad method, and the steel-clad method is the best among the three methods.

If you want the blade of patterned steel, then you need to divide the poured sword body into two, and repeatedly fold and forge, which is the method of tempering the short knife before you form, you can add a variety of other properties to strengthen the sword body before the sword body is formed, some materials can increase the hardness, and some can make it soft, each material is different, it depends on your needs at the time to match.

After the sword body is formed, find a steel of other materials, stack it on the sword body, and vigorously hammer it to fuse it together, which is also the most difficult, not only to ensure the fusion of the metal, but also to ensure that the shape of the sword body will not change, so be especially careful.

If this step is successful, it will be much easier to follow up with the cover of the blade as needed, the so-called covering blade is to use specially blended clay, cover the blade, adjust the thickness, heat to a fixed temperature, and then quench.

The exposed blade cools rapidly due to the temperature, which improves its flexibility and makes it tougher in combat, while the soil-covered blade part retains good rigidity, combining rigidity and softness, and harmonizing yin and yang, which is the basis for building a divine weapon. "The Great Elder explained to Lin Xingyu the common sense and knowledge of sword forging while he waited.

Lin Xingyu listened carefully to what the Great Elder said, and nodded from time to time, it was not easy to get the guidance of the Great Elder. Moreover, now it is time to repair the desolation of the ancient earthquake flood, and the Great Elder said that of course he must listen carefully.

"The same is true for repairing weapons, weapons like this are integrally formed, the whole body is made of the same material, there are some defects, the advantage is that the material is hard and strong, as long as the material is good, it is difficult to leave scars on the weapon, the disadvantage is that the toughness is poor, easy to break, and there will be a lot of small scratches. The Great Elder continued to sort the materials on the ground, staring at the desolation and talking without looking back.

Lin Xingyu approached the furnace eye and took a closer look, it was indeed as the Great Elder said, there was only one sword mark on the body of the barren man, and there were no other large scars, but small scratches were densely packed all over the body of the spear.

The Grand Elder threw the three masks onto the other furnace.

"There are many ways to repair the weapon if it is broken, but even if it is repaired, the overall toughness and strength are much worse, and the best way is to re-forge all the weapons to make the overall material, toughness, and strength of the weapon consistent, so that it can be repaired to the greatest extent. However, the material of this gun is relatively special, if you want to smelt and reforge it all, I am afraid that it will not work in a short time, but the repair is very fast. ”

Lin Xingyu pulled the bellows and thought while answering the sound.

About half an hour later, the broken barrenness was a little shiny, still as black as ink, and the three grimace masks were also a little shiny, and the material felt similar.

In another half an hour, the desolation was already red, and so were the three masks.

Seeing that the desolation was almost burned, the great elder took the tools on the side, took out one of the sections and put it on the desk and hammered it at the fracture, each hammer fell with the right force, the position was impartial, and the method of shooting was also extremely elegant.

The material of the desolate looked a little special, and the place where it was hammered became more and more red, and the Great Elder kept turning the desolate while hammering it, making sure that every place could be hammered.

It seems that this is done after the Great Elder found out that the Desolate Worm would change color after being beaten, Lin Xingyu saw a trace of joy in the Great Elder's eyes, and continued to hammer to other places, the place where the Desolate Hurricane was hammered many times became blood red, and as the Great Elder's hammer kept falling, soon, half of the Desolate Shaft had all changed color.

Time passed imperceptibly, minute by minute.

After a short time, the Great Elder picked up the blood-red desolation of his whole body, looked up and down for a long time, carefully inspected every place, and made sure that every place had changed color, before he continued to throw it back on the stove and continue to bake.

The remaining half of the Great Elder of the Desolation used the same method to make it all blood red, and then threw it back on the stove, only to take the Butterfly Mask that had been burned to a bright point, the mask was burned for a long time, and became very soft, and after a few hammers, it became flat and flat, but it did not become blood red like the desolation. The Great Elder shook his head in disappointment, stacked the three masks on top of each other and threw them back into the furnace to continue burning.

"Pull harder! As he spoke, the Great Elder threw a few strange ingredients into the furnace, and the fire was suppressed, and soon it rose again, burning even more vigorously.

After waiting for a full hour, the Great Elder took the two barren pieces again, connected them together, sprinkled with several metal powders, fixed them on the desk, raised the sledgehammer high, smashed it down, and then used a small shovel to pile the splashed metal powder back, and continued to hammer, hammering more than thirty times, the joints of the barren were deformed, but it seemed that they were indeed connected together.

The Great Elder put the barren water on the stove again, and continued to burn the joints with the fire, the Great Elder went unhurriedly to bring a cup of tea, sat aside and drank it slowly, Lin Xingyu, who pulled the bellows, was already sweating profusely, and he didn't even drink a sip of water, he was very dissatisfied with the inhumane behavior of the Great Elder, but there was no way, who let the Great Elder help him repair the barrenness, bear it.

The red color of the desolate body did not go down, but became brighter and brighter as the flames burned.

Lin Xingyu kept pulling the bellows all the time to keep the fire alive, and the great elder didn't help when he tasted the tea, looking at it with a smile, as if he was looking at how strong Lin Xingyu's endurance was, how good his body was, how long the bellows could be pulled, and whether he would be tired to death.

After nearly two hours, the Great Elder used tools to transfer the barren to the desk again, while fixing the barren on the desk with a clamp, fixing the barren with a kind of annular clamp at the end of the gun shaft, and then hammering the clamp with a hammer with uniform force, every three hammer blows, he had to run to see the connection of the barren place, Lin Xingyu saw that the connection was slowly hammered into a bulge, thinking that it was because the fracture was burned for a long time, it was softer than other positions, so it would be the first to deform here.

The Great Elder then took several kinds of metal powder, stacked them at the barren joint, hammered them repeatedly, and after deformation, he took out the grimace mask that had burned to the point of being about to melt, wrapped it in it, and then continued to hammer it. It was not until the deformation was severe that the desolation was put back on the furnace and continued to be calcined, and the remaining part of the mask continued to be thrown back into the furnace.

After operating like this five times, Lin Xingyu has lost his temper when he pulls the bellows, the great elder is leisurely, he should eat, drink tea and drink tea, he told Lin Xingyu that the fire in the furnace can't be small, Lin Xingyu pulled the bellows with his life, and he didn't dare to slack off.

The Great Elder repaired the junction of the desolate for the sixth time, and there was not much left of the grimace mask, and the desolate seemed to have been repaired, and it was the domineering spear again, but the repair position in the middle was black, and the sides were blood red, which looked a little strange.

In front of the desk, the Great Elder used a small hammer to carefully knock the black connection in the middle, Every time the small hammer was struck, it had to be rotated once, and it lasted for five hours, in Lin Xingyu's opinion, the barren was obviously repaired, and the connection was already very rounded, I don't know why the Great Elder was still beating, and Lin Xingyu also quietly touched the body of the gun, the barren was already cold, and the color of the cooled barren was back to as usual, and the whole body was pitch black, and there was no damage or scars to be seen.

It wasn't until the Great Elder showed a satisfied look that he stopped, and stroked the spear up and down with one hand to make sure that the spear was the same up and down, there was no difference in the slightest, and the feel was exactly the same.

After playing a few tricks with the spear, and once again making sure that there was no problem, he threw the spear on the stove again and continued to calcine.

Lin Xingyu was curious, but he didn't ask, it seemed that only the finishing work was left, so he pulled the bellows even harder, there was no need to slack off at this time, and the success fell short.

The desolation did not turn red after being hit by fire again, and it seemed that it was blood-red all over before that, and it only showed up when it was hammered.

The fire burned for an hour, and when the Great Elder saw that it was almost over, he pulled Lin Xingyu's hand, Lin Xingyu instinctively pulled his hand back, and he didn't resist, and let the Great Elder grab it, I don't know what it means.

The Great Elder took out his knife and slashed it at Lin Xingyu's hand, causing blood to flow on the spear, making a clattering sound and white smoke rising.

"Great Elder, what are you doing here?" Lin Xingyu asked suspiciously.

"It's okay, I just want to see if such a weapon can recognize the master!" the Great Elder explained.

This gun is not mine, it is my friend's. Lin Xingyu's tone was anxious.

"It's okay, it's so easy to become a divine weapon, don't worry!" said the Great Elder.

"Are you alright?"

"It's fine!"

"Are you alright?"

"It's all right!"

"Are you sure it's okay?"

"Get out, you talker, don't interfere with the old man's work. ”

Lin Xingyu was kicked by the Great Elder outside the sword-forging room.

He couldn't go in again, so he could only wait patiently outside, and in less than an hour, the Great Elder walked out with a spear, the body of the spear was as black as ink, and the tip of the spear was cold, it looked like it was still the same barren as before, but it seemed to be a little different.

The Great Elder threw the desolate water out, Lin Xingyu took it, and the huge force caused the desolate to shake twice in Lin Xingyu's hand, and then returned to calm.
